Wholesale prices for uniform fiber optic gratings (FBGs) in France typically range from €20 to €150 per unit, depending on specifications, quantity, and packaging.

Price Factors

The cost of fiber Bragg gratings depends on several factors:

• Type of grating: Standard uniform FBGs are generally less expensive than chirped or multi-grating arrays .
• Wavelength precision and reflectivity: High-accuracy gratings with narrow bandwidths (<0.2 nm) or high reflectivity (90–99%) command higher prices .
• Fiber type and packaging: Bare fiber gratings are cheaper, while pigtail or packaged gratings with connectors increase the cost .
• Quantity: Bulk orders reduce the per-unit price, with discounts often available for orders of 50–100 units or more.
